Research suggests that even mild sleep restriction can alter children's initial stages of speech perception, leading to disruptions in cognitive and linguistic functioning. Children need adequate sleep to develop essential skills for reading and language comprehension.
A simple test combines medical history, cognitive testing, and physical examination to predict dementia risk within six years. The 14-point index is accurate in predicting dementia with 87 percent accuracy.
Researchers at Cambridge University have developed an effective new method to test cognitive decline in mice with Huntington's disease using an automated touch screen. The tool allows for minimal movement by the mouse and is less stressful, making it a valuable asset in studying neurological disorders.
A study found that African-American parents' messages to their children about race vary depending on the neighborhood, with high-risk neighborhoods associated with better cognitive development. Promoting mistrust of other races was linked to behavior problems in low-risk but not high-risk neighborhoods.
The study reveals that 1- and 3-year-old children, as well as great apes, prefer a place-based strategy to remember hidden items, while humans reassess this preference with age. This suggests that some evolved cognitive strategies are masked early on in human development.
Researchers found that human infants and all great apes exhibit identical preferences for remembering where things are hidden. However, this preference shifts in 3-year-old human children, indicating a uniquely human developmental trajectory. The study provides insight into the evolution of human cognitive abilities and tendencies.
Researchers found that physical symptoms of frailty are often reversible and can be addressed through early intervention. The study, published in Archives of Internal Medicine, included 754 participants aged 70 or older and found high rates of recovery from frailty.
The Harvard Center for Risk Analysis examines the health effects of fish consumption, finding that moderate intake reduces stroke risk by 17% and coronary heart disease mortality by 3.9%. However, high mercury exposure may harm cognitive development.
The frontal cortex, a brain region controlling multi-tasking, continues to develop until age 17. The ability to remember single pieces of spatial information develops by age 11-12, while strategic self-organized thinking takes longer to mature.
A year-long study at Case Western Reserve University found that 'responsive teaching' strategies improved parents' interactions with autistic children and enhanced their developmental growth. The study showed a 60% increase in cognitive development and a 150% increase in language development among participants.
Researchers developed a novel metal-protein attenuating compound (MPAC) to target beta-amyloid interactions and slow cognitive decline. The pilot phase 2 clinical trial found that plasma beta-amyloid levels declined in patients taking the compound, while those on placebo levels increased.
Research suggests that breastfeeding duration may impact cognitive development. Children breastfed for less than three months were more likely to score below average on mental skills and total intelligence at ages 13 months and 5 years. The study controlled for factors like mother's age, education, and smoking habit.
Eight-month-old babies demonstrate ability to bind attributes to form a whole object, as seen in the Kanizsa Square test. This skill, previously thought to develop later in childhood, reveals insights into early infant development and cognitive processing.
The Digital Childhood conference explores how interactive technologies influence child development, aiming to promote healthy growth and development. Experts in cognitive, social, and emotional child development will discuss the benefits and risks of technology engagement for children.
A study found that people with Alzheimer's disease were 50% more likely to have depression symptoms than those without the disease. Depression symptoms such as lack of interest and loss of energy were three times more common in those who later developed Alzheimer's.
A University of Michigan study found that older Americans with depressive symptoms are at a higher risk of developing new diseases within two years, comparable to those who smoke. Physical limitations and multiple symptoms of depression also significantly increase the likelihood of developing new disease.
A UK study found that breast-feeding significantly boosts cognitive development in babies, with benefits seen as early as 6 months and sustained through 15 years of age. The study analyzed data from 20 published reports and found that breast milk provides essential nutrients required for rapid brain development.
A recent study by Brown University researchers has found a link between agrin protein and Alzheimer's disease plaques. The protein, involved in nervous system development, may play a role in the disease's progression.
Pediatric researcher Holly A. Ruff warns against applying large-group study findings to explain individual behavior, citing limitations in IQ testing and the complexity of vulnerability/resilience. Vulnerable children from disadvantaged backgrounds may face additional risk factors such as poor nutrition and lack of protective factors.
Researchers found that lower precombat and current intelligence were associated with PTSD symptoms among Vietnam veterans. Lower intelligence may lead to increased feelings of overwhelm and helplessness, increasing the risk for chronic PTSD.
Research reveals family characteristics and early child care experiences have a greater impact on the mother-child relationship than non-maternal child care. High-quality care reduces negative effects, but family traits and child temperaments play a significant role.
The NICHD study found that high-quality child care in the first three years of life is positively related to early cognitive and language development. Children in center care with positive caregiver-child interaction performed better on cognitive and language measures.
A twin study by Yale University psychologist J. Steven Reznick found that environment plays a greater role in how many words a child understands than genetic factors. The study also showed that language comprehension rather than spoken language at ages 14 and 20 months predicts intelligence test scores at 24 months.
Researchers from the University of Washington have developed a reproducible method demonstrating that subliminal messages can influence human cognition. The technique, called the response window technique, uses a brief flicker of time to test unconscious cognition on over 300 volunteer subjects.
